Channels django nginx 502


I ran into a problem once I install and add "channels" to the settings and after that to the asgi file. Server crashes, I get 502 and nginx won't start. How can I add these channels and start working already

ASGI_APPLICATION = "mysite.asgi.application"

application = ProtocolTypeRouter({
"http": get_asgi_application(),
# Just HTTP for now. (We can add other protocols later.)
# WebSocket chat handler
"websocket": AuthMiddlewareStack(
    URLRouter([
        
    ])
),

})

help, I'm sure a lot of people have come across this, thanks


Solution

  • Did you configure Nginx properly? Below is a sample Nginx config.

    upstream channels-backend {
        server localhost:8000;
    }
    ...
    server {
        ...
        location / {
            try_files $uri @proxy_to_app;
        }
        ...
        location @proxy_to_app {
            proxy_pass http://channels-backend;
    
            proxy_http_version 1.1;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection "upgrade";
    
            proxy_redirect off;
            proxy_set_header Host $host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header X-Forwarded-Host $server_name;
        }
        ...
    }
